Uncomplex has updated its Gmail client, Mailplane, with support for Gmail’s recently released Priority Inbox feature, a new ‘unseen’ message counter, some minor bug fixes, and more.

Mailplane is a dedicated Gmail client that uses WebKit to give you the native Gmail interface in a standalone program. It essentially gives you the benefits of using Gmail with a web browser—like labels, conversation views, Google Talk—as well as those of a standalone email client, such as integration with OS X, and Dock icon notifications.

With version 2.2, Mailplane now supports Gmail’s Priority Inbox, a new feature that splits your inbox into three sections—”Important and unread,” “Starred”, and “Everything else”—and intelligently sorts your incoming emails into the most appropriate section. Mailplane 2.2 gives you the option to set your Priority Inbox as your default inbox, so if you’re a fan of this feature, you’ll be able to use it just as you would in a Web browser.

Mailplane has also been given a feature called Rapportive, which replaces the sponsored links you normally see on the right-hand side of the client with useful contact information. For instance, when viewing a conversation, Rapportive displays your contact’s data from Twitter, Facebook, LinkedIn, and other sites.

Also new is an ‘unseen’ message counter, which shows the number of new messages since you last visited the account, as opposed to just the total number of messages you haven’t yet viewed. Mailplane has also added the Safari-like option to automatically open ‘safe’ attachments after you download them.
